Chris,
Very glad to hear you found the actual problem. It IS a mystery as to why it changed
over time.
A couple questions:
1- Had you done any fuel pump maintenance before this happened? What is the total
gasket thickness now?
2- Are your electric and mechanical fuel pumps in series or parallel?
3- Do you normally run the electric during all phases of flight?
FWIW, my electric pump is plumbed in parallel with the mechanical and I use the
electric to fill the float bowl before starting and during approach and take-off.
I know the Facet is a 100% duty cycle pump which could be run full time but
it is an old habit of mine not to use it except as stated.
Also, I've never removed my fuel pump so don't know how much gasket is there and
I don't have a fuel pressure gage installed so don't know what it is producing.
I think I'll ckeck it out during next condition inspection.

Started my engine for the first time yesterday. It had been sitting in the basement

some throttle adjustments and prop pitch changes. I had about 5700 rpm and still
had some throttle to go. I used 10 degree angle on a 70" three blade warp

The manual for the SportCruiser says that Rotax 912 ULS should be operated
normal cruise at 4,800-5,300 but with 100LL 5,000-5,300. I assume this is to
deal with the high lead content of 100LL. Interesting.

<< Push about 3/32" of cable through and then rat tail it severely with
a small tool ... then solder it. >>
Jimmy -
The exact thing happened to me a few years ago, on my Mark-3. Throttle
cable slipped thru the ferrule. Fortunately for me, on the 912, the
carbs spring to full throttle if the cable lets go. This gave me the
fortunate opportunity to fly back to my airport, enter the pattern, and
shut down the engine on downwind, making for and easy deadstick pattern
and landing.
Richard Pike shared the same advice with me (above) at the time , on
fixing the cable/ferrule interface. It's an excellent solution -
guaranteed not to ever pull thru again. That's how I fixed it on my
Kolb.
Glad to hear you exercised excellent judgment, and made a safe landing
without damage to you or your Firestar.

Thanks John. Do you remember what angle you used?
**********************************
Not for sure.
12 to 12.5 sounds pretty good. Each engine and prop will have its own
setting. Main thing when you get it dialed in close is to insure all three
blades are set the same, even if it was over or under 5500 WOT straight and
level flight, by just a little bit. I doubt most of our tachs are all that
accurate anyhow. I usually do a prop tach check when I adjust my prop to
insure my engine tach is close.

I'll try 12 degrees and see what happens. I have an E.I.S. and also a tach guage.
They were within about 25 rpm of each other as best I could see so I'm comfortable
that it's a good reading.
The Rotax manual that I have ok's a max. continuous speed of 5500 rpm but 5 minutes
only at 5800 rpm.

Chris
Davis
Chris D/Gang:
1987, I was flying my brand new FS without brakes and with standard round
lift struts out of Gantt IAP, all 600 feet of it.
I finally saved up enough money to buy 4130 streamlined tubing for new lift
struts. Brother Jim welded them up for me, I got them prepped, painted, and
installed.
On my first test flight I was amazed at how stable and solid the FS felt.
The round aluminum struts were constantly dancing in flight. On my first
landing I had to go around. I ran out of airstrip. With no brakes to slow
me down, and a hefty increase in glide and reduction in drag, I had to
rethink my landings. Was time for brakes. ;-( By Spring 1988, I had
brakes and longer heat treated 4130 gear legs, 35.5" long. I chose that
length because Lindberg Heat Treating in Orlando, FL, could only go 36". By
being able to get the nose higher during landing and roll out I was able to
use the bottom of the wing to help slow me down, plus my new Hegar Brakes.

Rex
Rex/Gang:
That is why we pitch for 5500 straight and level WOT with a fixed pitch or
ground adjustable prop. If we pitch for 5800 we have terrific climb and
poor cruise. Pitch for 5500 and we get the best climb and cruise combo.
5800 could be used for 5 min if you had an inflight adjustable prop, which
would be a nice toy, but not really necessary to have fun and fly where you
want to. I have never had a problem being pitched for 5500.

- John- Very interesting info about your Firestar.- I have a set of ste
el (!) streamlined struts, almost 10 pounds for the pair.- I intended to
swap them out for round aluminum to cut some weight.- Once they are off,
I will probably put them up for grabs.- Your comment about your 600 foot
field got my attention.- My spot for a field at my place in Vt. is about
600 to 700 feet long.- It's on top of a small hill, with the ground being
lower at both ends.- The prevailing wind is aligned with the runway.-
I was wondering about the necessity of brakes, and now I know.- I wonder
if Richard Pike still has the old FS brakes he mentioned.-

I think the reduction in drag, absence of vibration, and good solid feel of
the steel streamlined struts will far outweigh the difference in weight,
which probably will not be that much. Definitely not progressing going
round aluminum.

seems that springs loose tension after time.... I am puzzled on how you

OK..
Our theory on the spring is this....as the spring gets rusty from condensation
it gets more brittle and harder thusly,making more pressure as it pushes the
fuel into the carb...cutting it off,making it shorter also made the spring weaker
and reducing the pressure...you think ???When I get the new spring ,I am
going to rust proof it just for the heck of it then re-install it and take another
pressure reading....

| Subject: | Re: Kolb/Jabiru carb overflow |
Contrary view...Wow there are thousands of those engines in service, lots with
very high hours, and yours is the first to suffer "rusty fuel pump spring hardness"?
I am unaware of the metallurgy that leads to increased elastic modulus
from rusted steel surface damage. Maybe something hangs up on the spring movement
or a diaphragm movement......I think I would look again for maybe a vacuum
or vent leak in the induction systems that develops with temperature differential.
Best of luck..

weaker and reducing the pressure...you think ???When I get the new spring ,I
am going to rust proof it just for the heck of it then re-install it and take
another pressure reading....

Kolbs (in the US at least) don't have type certificates, which are only for
factory produced aircraft. Kolbs here are certificated in the
Experimental category, with only an airworthiness certificate.

| Subject: | Firestar winter flying video |
Friends,
I recently uploaded a video, made years ago, to YouTube. It was my first
attempt at video and isn't that great or sharp but it does give an idea of how
flying is done up north in winter.
http://www.youtube.com/watch?v=-a834qGn-OU
Enjoy, I hope.

Even the sun looks cold up there in the Far North.
Very nice flying and video.
Be glad when the weather straightens itself out down here in the sunny south
and I can go fly a little.
